Feature

●Buck module supports built-in over-temperature, over-current and output short circuit protection. The step down power supply module has a positioning hole that can be attached to a suitable place as required.
●The voltage converter supports wide voltage input, the input voltage range is 12V to 120V DC. It has a potentiometer that allows you to adjust the output voltage of the power module.
●If the difference between input voltage and output voltage is less than 5V, the output is unstable or there is no output. Try to leave a certain leeway when using, enter the battery to consider the highest voltage value when the battery is fully charged.
●This module is versatile. The usage scenarios are DIY regulated power supply, charging different batteries, operating electronic devices, controlling high-performance LEDs etc.
●Customer service: thanks for your purchase. If you have any problem, please feel free to contact us at any time. We promise you the satisfactory solutions within 24 hours.


Description

1. Description:

It is a DC DC step down module. Step-down module input voltage DC 12V-120V, output voltage DC 1.25V-48V.

2. Parameters:

1) Product Name: DC Downward Module

Input voltage: DC 12V-120V.

3). Output Voltage: DC 1.5V-48V

4). Input and Output Voltage Difference:5V (guarantee the output voltage is 5V less than the input voltage during use)

5). Output Current: 1.5A (Max)

6). Switching frequency: 110 KHz.

7). Positioning hole: 2 mm.

8). Working temperature: -40℃ ~ 85℃

9). Working humidity: 5% ~ 95% RH

10). Size: 44 x 20 x 14 mm.

3. Connection method:

1).IN+: input positive

2) IN-: input negative pole.

Out+: output positive

Output: output negative pole.

4. Instructions:

1) First connect the cable between the module and the power supply, and then turn on the power supply. (When the input port is under voltage and wired, it may easily cause sparks, especially if the input voltage is high even burn the pads of the module).

2) For the first use, you need to connect to a power supply of more than 30 V and measure with a multimeter or voltmeter whether the output voltage of the module matches the voltage required by the device.

3) The electrical equipment (load) is connected to the output end of the module.

5. Package contents:

1) 1 x DC downward module.
